Modular Multilevel Converter with Distributed Galvanic Insulation: A Decentralized Voltage Balancing Algorithm with Smart Gate Drivers
Résumé
A novel Distributed Galvanic Insulation (DGI) concept is presented in that paper. It implies a daisy chaining of the drivers. Applied to MMC, the DGI forbids the use of classical Voltage Balancing Algorithms. A new algorithm, directly integrated on the gate drivers, is proposed for DGI-MMC and validated by simulation.
